For the equation 3(7+x)=3x+k, what value of k will create an equation with infinitely many solutions?

Answers

Answer 1

Answer: k = 21

Step-by-step explanation:

3(7 + x) = 3x + k

21 + 3x = 3x + k

21 + 3x - 3x = 3x + k - 3x

k = 21

Ali Clara and Shane raise money for new books for the school library all Ellie rays 20% more than Clara and $58 more than Shan Claries 1/4 times

Answers

Answer:

a. $435

b. 33.33%

Step-by-step explanation:

P.S - The exact question is -

Let Clara raised money = x

As given,

Ali raised 20% more than Clara

⇒Ali raised money =  [tex]x + \frac{20}{100}x = x + \frac{1}{5} x = \frac{6}{5}x[/tex]

Also given,

Clara raised [tex]\frac{1}{4}[/tex] times more than Shan

Clara raised money = Shan raise money + [tex]\frac{1}{4}[/tex] times shan raired money

⇒Clara raised money = [tex]\frac{5}{4}[/tex]  Shan raised money

⇒Shan raised money =  [tex]\frac{4}{5}[/tex] times Clara

⇒Shan raised money = [tex]\frac{4}{5}[/tex] x

As given,

Ali raised $58 more than shan

⇒[tex]\frac{6}{5}x = \frac{4}{5}x + 58[/tex]

⇒[tex]\frac{6}{5}x -\frac{4}{5} x = 58[/tex]

⇒[tex]\frac{2}{5}x = 58[/tex]

⇒x = (29)(5) = $145

∴ we get

Clara raised money = x = $145

Ali raised money = [tex]\frac{6}{5}x[/tex] = $174

Shan raised money =[tex]\frac{4}{5}[/tex] x  = $116

a.)

Total raised money = $145 + 174 + 116 = $435

b.)

Percentage of money Clara raised = [tex]\frac{145}{435}[/tex]×100% = [tex]\frac{1}{3}[/tex]×100% = 33.33%

Charmaine has 17 cars available to rent. Let C be the number of cars she would have left after renting R of them.

Answers

Answer:

C = 17 - R

Step-by-step explanation:

In this scenario, 17 cars would be the initial starting point. While C would be the final number of cars, meaning that our equation would have to equal C. If she rents R number of cars then this number is being subtracted from the initial number of cars because Charmaine would no longer have them in his/her possession. Therefore, it is being subtracted. Using this information we can create the following equation.

C = 17 - R

5x + 50 = y and 4x + 46 = y

5x – 50 = y and 4x – 46 = y

5 – 50x = y and 4 – 46x = y

Answers

Answer:

50 – 5x = y and 46 – 4x = y, is your answer

ANSWER FOR BRAINIEST

Answers

THE ANSWER IS: y=3/2x+1

to find a line that is perpendicular, invert the slope and multiply by -1
so the original slope is -2/3,
invert it to get -3/2 then multiply by -1 to get 3/2

put the given point (-2,-2) and the new slope into point intercept form: y+2=3/2(x+2)

rewrite in standard form to get y=3/2x+1

Kira drove 522 miles in 9 hours.
At the same rate, how many miles would she drive in 7 hours?

Answers

GIven:522 miles in 9 hours.

So if we divide 522 by 9 we get that Kira drives 58 miles per hour.

Now in 7 hours Kira just drives 7 times that which means Kira drives.

58*7=406 miles

Hope this helped!

Step-by-step explanation:

Distance travelled in 9 hours = 522 miles

Distance travelled in 1 hour = 522/9 = 58 miles

Distance travelled in 7 hours = 7 * 58 = 406 miles

Answer:

[tex]y = \frac{2}{5} x + 3[/tex]

Step-by-step explanation:

2x - 5y = -15

Firstly, you will need to isolate the variable you are solving for, in this case, y.

2x - 2x - 5y = -15 - 2x

-5y = -15 - 2x

-5y/-5 = -15/-5 - 2x/-5

A negative divided or multiplied by a negative is positive.

[tex]y = 3 + \frac{2}{5} x[/tex]

Rearrange.

[tex]y = \frac{2}{5} x +3[/tex]

After 5 hours, how far apart are the boats? Label the distance(s) on your drawing from the first problem.

Answers

Answer:

The distance between them is 277.84 m

Step-by-step explanation:

See comment for complete question.

Given

Boat A:

[tex]Speed = 24mph[/tex]

[tex]\angle A = 340^{\circ}[/tex]

Boat B:

[tex]Speed = 35mph[/tex]

[tex]\angle B = 200^{\circ}[/tex]

[tex]Time = 5hr[/tex]

First, we calculate the distance traveled by both boats in 5 hours

[tex]Distance= Speed * Time[/tex]

[tex]Boat\ A = 24mph * 5hr = 120m[/tex]

[tex]Boat\ B = 35mph * 5hr = 175m[/tex]

For more clarity, I'll make use of the attached image to represent the system.

From the attachment, we are to calculate distance C, but first we calculate the angle between them.

[tex]\theta = 340^{\circ} - 200^{\circ}[/tex]

[tex]\theta = 140^{\circ}[/tex]

C is then calculated using cosine law:

[tex]C^2 = A^2 + B^2 - 2BC\ Cos\theta[/tex]

This gives:

[tex]C^2 = 120^2 + 175^2 - 2*120*175\ Cos(140^{\circ})[/tex]

[tex]C^2 = 120^2 + 175^2 - 2*120*175*-0.7660[/tex]

[tex]C^2 = 14400 + 30625 + 32172[/tex]

[tex]C^2 = 77197[/tex]

Take square root of both sides:

[tex]C = \sqrt{77197[/tex]

[tex]C = 277.84[/tex]

The distance between them is 277.84 m
